mmm...exploiting old memories. But why it looks so shitty? PSP graphic quality.

Some indies and kickstarter games don't have high end visuals too but they compansate it with art style and other things. And this..It just didn't get even a stepp better than Dungeon Keeper 2. It's ugly and copy-paste

It's a spiritual successor to Dungeon Keeper, so it is absolutely meant to look like DK1 and DK2.

Also, it's running at over 15x the resolution of the PSP (seriously). The PSP ran at 480 x 272, this can go beyond 1920x1080.

Taking into account that these guys are basically making a triple-A game with a shoestring budget. I'd say they're doing okay. I have some issues with some of their graphics choices, but they've acheived a very clean and WOW-like aesthetic which is totally acceptable:
